Instructions:

- Bake graham cracker crusts in the preheated oven until golden brown.
- Whisk together dry ingredients. In a separate bowl, combine wet ingredients. Gradually add wet ingredients to dry ingredients, mixing until just combined. Add boiling water and mix until smooth.
- Fill cupcake liners about 2/3 full. Bake until a toothpick inserted into the center comes out clean.
- Let cupcakes cool completely in the muffin tin before transferring to a wire rack.
- Heat heavy cream in a saucepan. Pour over chopped chocolate and let stand for a minute. Stir until smooth and glossy. Let cool and thicken slightly.
- Core each cupcake and fill with chocolate ganache.
- Beat softened butter until smooth and creamy. Gradually add powdered sugar and cocoa powder, alternating with heavy cream. Beat in vanilla extract.
- Frost each cupcake with chocolate frosting using a piping bag or spatula.
- Shape marshmallows into ghosts, or use store-bought marshmallows.
- Place a marshmallow ghost on top of each frosted cupcake.
- Lightly toast the marshmallow ghosts using a kitchen torch, until golden brown. Add chocolate chips for the ghost eyes.
